Frequently Asked Questions - AirflowTestMaster Laserliner

How to measure wind speed with the AirflowTestMaster?

Power on the device, then press the MODE key until VEL is displayed. Place the device parallel to the air stream, close to it. Use the UNIT key to change units (m/s, km/h, etc.).

How to change the measurement unit?

Press the UNIT key several times to cycle through available units: m/s, km/h, mil/h, ft/m, ft/s, knots. For temperature, press and hold UNIT to switch between °C and °F.

How to use the HOLD function?

Press the HOLD key to freeze the current measured value on the display. Press again to deactivate. Note: MODE, UNIT and MIN/MAX functions are disabled while HOLD is active.

What to do if the low battery icon appears?

Replace the battery with a new 9V (6F22) type. Open the battery compartment, observe the indicated polarity (+/-).

How to transfer data to a PC?

Install the software and drivers from the provided CD. Connect the device to the PC via USB, press and hold the USB key to activate the link. The software displays real-time values.

How to set the area for volumetric flow calculation?

In volumetric flow mode, press MODE until AREA is displayed. The first digit flashes. Use ▲ (plus) and SET (decimal) to enter the area in m² or ft². A beep confirms completion.

What is the accuracy of wind speed measurement?

The accuracy is ±(2.0% + 50 digits) over the entire range. For example, for a measurement of 10.00 m/s, the error can be approximately ±0.70 m/s.

How to enable or disable the auto power off?

The auto power off is enabled by default after 20 minutes of inactivity. To disable it, press and hold the MODE key while powering on until the AUTO-OFF icon disappears.

What do the dew point and wet bulb displays mean?

The dew point is the temperature at which air becomes saturated. The wet bulb temperature is measured by a wet thermometer. Press and hold DP/WP to toggle between these values.

How to clean the anemometer?

Use a dry, soft cloth. Do not use solvents or water. Avoid immersing the device. Protect the vane from shocks.

USER MANUAL AirflowTestMaster Laserliner

Read the operating instructions and the enclosed brochure „Guarantee and additional notices" completely. Follow the instructions they contain. Safely keep these documents for future reference.

Function/Application

The anemometer is used to measure air flow rates, volumetric flow rates and wind speeds. Integrated sensors constantly register the ambient temperature, relative humidity and calculate the dew point temperature. The USB interface additionally permits realtime logging on a PC.

4 Room climate

When switched on, the ambient temperature and relative humidity are permanently shown on the display. The dew point or wet-bulb temperature can also be set in place of the ambient temperature. Change between the different values by pressing and holding the „DP/WP" button.

You can set the units ^ C / ^ by pressing and holding the "UNIT" button.

Please refer to the following instructions for use when determining wind speed or volumetric flow rate:

• Position the device parallel to the flow source
• Place the device as close as possible to the flow source
• Use the MAX function to determine the position with the strongest air flow
• Avoid direct sunlight during measurement

Wind speed

After switching on by pressing the MODE" button, activate the "VEL" function. Press the "UNIT" button repeatedly to change the units: m/s (metres per second), km/h (kilometres per hour), mil/h (miles per hour), ft/m (feet per minute), ft/s (feet per second), knots.

Press the MAX/MIN button to display the highest and/or lowest value during a measurement. As its name suggests, the HOLD button enables you to hold the current measured value.

The „MODE“, „UNIT“ and „MIN/MAX“ functions are deactivated while the „HOLD“ function is activated. These functions are available again after pressing the „HOLD“ button once more.

6 Volumetric flow

The outlet area of the flow source must first be defined before determining volumetric flow.

After switching on by pressing the MODE" button, activate the function for measuring volumetric flow until AREA" appears on the display. The first number begins to flash. Use the (+) and SET (change decimal place) buttons to enter the determined area.

The area can be set both in square metres (m^2) as well as in square feet (ft^2) . The end of the input is signalled by a double beep.

Activate the "FLOW" function by pressing the "MODE" button. After selecting the corresponding unit - CMM (cubic metres per minute), CFM (cubic feet per minute) and CMS (cubic metres per second) - press the "UNIT" button to determine the volumetric flow based on the set area.

The „MODE“, „UNIT“ and „MIN/MAX“ functions are deactivated while the „HOLD“ function is activated. These functions are available again after pressing the „HOLD“ button once more.

MIN/MAX/HOLD

The MAX function is activated by pressing the „MAX/MIN“ button. The measured value currently displayed corresponds to the largest measured value. Press the „MAX/MIN“ button again to activate the MIN function and show the smallest measured value. To deactivate „MAX/MIN“, press the button again until the value is no longer shown on the display.

Press the "HOLD" button to hold the current measured value on the display. Press the button again to deactivate this function.

USB transfer

Measured values can be transferred to a PC in realtime via the integrated USB interface. The values can then be stored and documented using the supplied software. First install the software and the corresponding drivers from the CD to the terminal unit. Follow the instructions for the installation routine. Once you have successfully installed the software, connect the measuring instrument to the PC and set up a USB connection.

Start the software and activate the USB function by pressing and holding the "USB" button. The software now shows the measured values both in numerical as well as in graphic form.

For further information on how to use the software, refer to the Help function that contains a detailed description of the functions.
